So I felt like making some logic stuff in minecraft... then I started making a half-adder... then a full adder... then 2 and 3 bit adders...

This project includes:
- OR gate example
- AND gate example
- XOR gate example
- Half adder example
- Full adder
- Two bit adders (2 bit inputs, 3 bit out)
- Three bit adders (3 bit inputs, 4 bit out)

Enjoy looking at and messing around with the calculators. More complicated caluculators can be made but while I was working on the three digit adder, I encountered problems of redstone current running out. The larger it is, the more of those problems you end up with and so I decided not to expand it any further.
EDIT: Okay. I did it. 4 bit adder complete. I'll do the 5 bit one before I upload.

I am aware that not everything is super compact. I wanted people to be able to see what was going on.

Binary guide:

Decimal	0001	0002	0004	0008
Binary	0001	0010	0100	1000

It continues on like that into infinity. 9 in binary would be 1001. 14 would be 1110. 3 would be 11.
